Lancôme has selected The Glass Polymer for the injection-moulded packaging of Secret de Vie. The packaging features wide-ranging properties, including gloss, absolute colourless crystal transparency, ultrasonic weldability and chemical resistance, and is produced by Auriplast.
The Secret de Vie cream jar comprises two spheres forming a bottom and lid screwed assembly, with both half spheres injection-moulded using hot-runner technology. Each half of the assembly is a double wall structure formed by ultrasonic welding, while an inner lacquered shell inserted into a transparent counterpart with high wall thickness creates the double wall. This means that the inner sphere appears to levitate inside the outer one, adding to the visual impact of the design.
According to Eastman Chemicals, the Glass Polymer's properties provide Secret de Vie with a luxuriousness thanks to its heavy feel and ability to remain transparent at thick diameters. The company claims that compared with other materials such as PMMA and styrenics, The Glass Polymer provides better fatigue resistance, crucial at the interface between the jar's bottom and lid.
